STR: 1. Tap URL bar to bring up Home panels 2. Start tapping between the different home panels Expected: App should display each panel when tapped Actual: App will crash after a short time -- Here is a partially symbolicated crash from crash-stats: https://crash-stats.mozilla.com/report/index/798d3053-872b-4d47-b266-222d62150819 I'm currently in the process of trying to get the UIKit framework symbols loaded as well.
Note: This occurred in build #36 Aurora
How often is this reproducible?
100% of the time when switching between panels quick. I might have narrowed it down. The issue as introduced between builds 34->35. I'm going to take this to see if there is a quick fix for 1.0 because crashes suck.
Couple of things: 1. Safer target/action. I was able to get crashes from the selector being called on an invalid/deallocated target. I've made the add/removal safer by binding them to the willAppear/didDisappear events. 2. Added checks to make sure we only call endRefreshing if we are refreshing. 3. Renamed the refresh method and target selector. Looking at https://crash-stats.mozilla.com/report/index/a04d4cb7-038e-435a-a203-ee0752150819#allthreads it seems that the crash is happening inside UIKit and might be a naming collision with 'refresh' considering it's a popular name for a method. Added just in case. I haven't been able to reproduce the crash with these fixes
